Principle of solar light technology
Jun 01, 2018

Solar energy Lamp Working principle is simple, make use of the solar cell with the principle of the photovoltaic effect, solar panel receives solar radiant energy in the daytime and transforms into the electric energy output, the charge and discharge controller is stored in the battery, the night when illumination degree reduces to 101ux, Solar panel open circuit voltage of 4.5V or so, charge and discharge controller detects this voltage value after the action, the battery to the lamp discharge. 

Battery discharge after 8.5h, charge and discharge control action, battery discharge end. The main function of charge and discharge controller is to protect the battery.
